24-bits/pixel BGR with 8 bits per channel as an ordered byte sequence, followed by a single byte of padding.

IMG_FMT_PKBE_XRGB8888

A big endian version of IMG_FMT_PKLE_XRGB8888

In addition to PKLE and PKBE variants listed above, there are PKHE and PKOE variants that make it easier to identify host-endian (HE) formats and other-endian (OE). So for example, if your code is executing on an x86 platform, IMG_FMT_PKHE_ARGB1555 equals IMG_FMT_PKLE_ARGB1555. Or on a ppcbe platform, IMG_FMT_PKOE_ARGB8888 equals IMG_FMT_PKLE_ARGB8888.
